But a Los Angeles City Council member, a longtime fan and other Harrison admirers are doing their part Wednesday, on what would have been the former Beatle’s 72nd birthday, to right a wrong committed last year when an insect infestation — yes, they were beetles — killed what was known as the George Harrison Tree.When word went out last year that the original tree had been felled by tree beetles, news quickly shot around the world and the story made international headlines.Councilman Tom LaBonge, whose Fourth District includes Griffith Park, helped plant the original tree in 2002, not long after Harrison died Nov. 29, 2001, in Los Angeles, from cancer at age 58.“We had a tribute on the steps of the observatory,” recalled LaBonge, now in his final term of office, “and several hundred people wrote notes, which we’ve collected in a book ‘We Remember George.’ ”
